Trait approach

Situational approach

behavior determined by situation or environment. Situation is more important at determinant then personality traits. ex: introvert being assertive during a mugging or football player being violent when he is not.

interactional approach

behavior determined by both person and the situational factors as well by interactions. How a person responds depends on environment and psychological traits. ex: hostile person at a football game will not be hostile in front of his mom but will in front of his friends.
